Disequilibrium, adaptation and the Norse settlement of Greenland

This research was supported by the University of Edinburgh ExEDE Doctoral Training Studentship and NSF grant numbers 1202692 and 1140106.There is increasing evidence to suggest that arctic cultures and ecosystems have followed non-linear responses to climate change. Norse Scandinavian farmers introduced agriculture to sub-arctic Greenland in the late tenth century, creating synanthropic landscapes and utilising seasonally abundant marine and terrestrial resources. Using a niche-construction framework and data from recent survey work, studies of diet, and regional-scale climate proxies we examine the potential mismatch between this imported agricultural niche and the constraints of the environment from the tenth to the fifteenth centuries. We argue that landscape modification conformed the Norse to a Scandinavian style of agriculture throughout settlement, structuring and limiting the efficacy of seasonal hunting strategies. Recent climate data provide evidence of sustained cooling from the mid thirteenth century and climate variation from the early fifteenth century. Archaeological evidence suggests that the Norse made incremental adjustments to the changing sub-arctic environment, but were limited by cultural adaptations made in past environments.Publisher PDFPeer reviewe

Who were the first urban settlers of Oslo? A discussion of early medieval urbanization based on isotopic analyses of human remains

This paper investigates the process of early urbanization in Oslo, Norway, during the initial period of early 11th–late 12th Century using a bioarchaeological approach. Through the use of isotope analyses performed on teeth and bone from 20 humans buried in Oslo during the first phases of urban settlement, individual dietary change and mobility are reconstructed. Oslo is traditionally perceived as one of many urban settlements initiated by royal power, and this paper contributes to this discussion by investigating the origin of the first settlers, and also how the early urban process affected their way of living. Results suggest that most individuals in the study were of local origin, and had a constant diet throughout life from childhood to its last phase. The absence of individual dietary change sharply contrasts the dynamic dietary patterns observed in people from the Viking age. Dietary variation between individuals does suggest, however, social differences among the early urban population of Oslo
